摘要
The goniometer for measuring finger reflex and hyperextension has a measuring plate (MP) and a pair of cooperating measuring arms (CM, KM). The longer of these is sufficiently long to allow it to be supported against the hand, with the measuring plate rotated by the index finger into a required position. An angular scale is marked on each side of the measuring plate (MP) the shorter measuring arm (KM) offset by 40 degrees from the scale zero point. A pointer (2) on either side of the measuring plate (MP) is coupled to the longer measuring arm (LM) with a fixation screw (FS) providing the rotation axis for the measuring plate (MP) and allowing the frictional resistance between the longer measuring arm (LM) and the measuring plate (MP) to the adjusted. ADVANTAGE - Allows single-handed use.
